4.Uses big.LITTLE technology

O+ Evo 4G

Samsung Galaxy S7 edge (Exynos 8890 Octa)

Using big.LITTLE technology, a chip can switch between two sets of processor cores in order to maximise performance and battery life. For example, when playing a game the more powerful cores will be used to increase performance, whereas checking email will use the less powerful cores to maximise battery life.

5.Has out-of-order execution

O+ Evo 4G

Samsung Galaxy S7 edge (Exynos 8890 Octa)

Out-of-order execution is used in CPUs to make use of instruction cycles that would normally be wasted due to delays.
